Various questions regarding SSD

[idata]

What is the best raid stripe size for the X25-E and X-25-M?

Will the existing line of Intel SSD's be compatible with Windows 7 TRIM command? If so when is this likely to happen?

If TRIM is going to be supported will it be supported via RAID?

Is there any update on the new 34nm SSD product line? When will specs be available?

Will the 34nm technology use the same controller or will it be a new controller?

EDIT:

I can now answer part of my own question. After extensive testing with IOmeter I have concluded that a 128k stripe size is going to work best for raid 0 in the vast majority of cases, and certainly for normal OS use. That is based on test results using two different controllers and stripe sizes ranging between 16k & 1042k. (Tests on one controller were limited to 256k due to limitations of the controller.) This involved a lot of work, for something that could easily have been explained.

Intel....

you are currently dealing with enthusiasts in your new SSD market, who are interested in the technology and want to know as much as possible about it. Why have the anonymous corporate attitude to your new and exciting product line? Why is there the party line of saying nothing about such an exciting product? (Even something as basic as letting people know they should be using AHCI and not IDE mode).MS seemed to have learnt that this is not the way to go with all the fantastic work they have done with Windows 7. Enthusiasts are raving about Windows 7 and that is going to really help Windows 7 launch to the mainstream with maximum impact.

Every now and then it is good to throw your (loyal) dog a bone 😉

Soon it will be on eBay 😉

There is nothing wrong with it, it just does not deliver to the optimised performance of the X25-e. I discussed it with Adaptec and they admitted that SSD required optimisations that had not been a focus with HHD.

I read your other post regarding the new drive release date....seems to be fud as nothing has since materialised. L

For some weird reason Intel do not seem to like to talk to their customers until a product is officially launched. Same thing with TRIM.

Well, as far as I know, IOP348 1200Mhz is the best RAID controller at the moment. If you can wait, just continue waiting If not, that's the best thing you can find that is able to saturate the speed of SSD

Getting my 5805Z soon Zero-maintenance......or shall I get a 51205 first and grab the SSD Cache upgrade when it's available?

Side track a little, what's purpose of the chip under the orange color heatsink?

afrosty, thanks for replying!

I have a serious question. What is the minimum requirement for a RAID controller to see significant benefits in using X25-E? What about X25-M?

We saw an abnormal performance issue with Intel Modular Server's storage controller module (SCM) originate from the LSI* 1068 and PM8399* devices.

This is the ATTO results with 6xX25-E 32GB:

This is worse than the performance of a single drive!

Would switching to X25-M help?

The OS we are using is Windows2008x64.

"We are currently looking at product intercept timelines for TRIM capabilities. Look for updates during announcements for upcoming product lines." Does this mean that existing solid state drives will not be able to use trim?

Hi Alan, Is this true? No TRIM support for 50nm drives? http://www.anandtech.com/cpuchipsets/showdoc.aspx?i=3605 Link
